inflated the quads tires to the gauge i bought,went to the track,two broken ribs latter,found that the tyres were under inflated,bought another gauge and got it right
Can't go wrong! Nitrogen does not escape as easily as Oxygen, and there is no moisture as you would typically get with a normal air compressor pumping up the tyres. Plus, there is less of a pressure change based on tyre temperature, so far less chance of a blow-out or change of tyre handling comfort characteristics, albeit a small difference, I firmly believe in the use of Nitrogen in tyres.
